Program crash

when I import an fbx file and start working the program freezes, I can no longer move or change parameters
I don’t think it’s a pc problem:
CPU: ryzen threadripper 2950x 16 cores
GPU: Nvidia GeForce RTX 3080 10GB

Hi there,

May I know if you’re using 4k monitor?
Also could you send me the scene file(the whole folder saved from D5 Render, including drs, assets, models) to my email -

Thank you
